A news summary based solely on the provided article body: The expansion of the human footprint over the past century has been explosive, with humans dominating the planet largely due to intelligence. This mastery has been achieved via self-reinforcing systems that have undermined the biosphere, chief among them the economic-growth imperative “invented” in the mid-20th century. The pursuit of growth as an end in itself is wedded to unrestrained technological advancement, fostering a reckless culture in the tech world, spurred by the pursuit of trillions of dollars in returns. Advances in AI have placed humanity on the verge of creating an intelligence that matches and eventually exceeds our own, with safety experts warning we may soon replace ourselves as Earth’s most intelligent species with a silicon-based one. Another scenario involves “humachination,” the melding of humans with robots, which is profoundly threatening to humanness. Michael D.B. Harvey holds out hope for an ironic salvation: limits to growth, with resource constraints hamstringing the humachination project. Since machine intelligence was first theorized, notables such as Alan Turing warned of its dangerous potential, determining that intelligence was “substrate independent.” Turing proposed the Turing test in 1950 to establish whether a machine could pass for a human in a verbal interaction, and 2014 marked a milestone in AI research when a chatbot at t.
